FEATURES

THE CLAYTON COIL The Clayton Pump has been designed specifically for the continuous supply of high-pressure and high-temperature feedwater to the Clayton Steam Generator and has exceptional durability. The pump does not have any glands or mechanical seals and the moving parts are semi-submerged in an oil reservoir. Faultless operation is achieved by the use of a reciprocating piston that pushes oil against a diaphragm that, in turn, moves water in a vertical column. The water inlet and outlet is at the top of the column so that heat from the water being pumped does not reach the pump mechanism. The complete assembly is housed in an extremely strong cast ductile iron block. The Clayton Pump is unsurpassed for long life, reliability and performance. The Clayton Coil has been developed for high heat transfer and long-term reliability. Its unique design allows water and heat to flow in opposite directions in a single pass. This counterflow pattern is the most efficient way to transfer heat energy and provides preheating of the incoming water. Each coil layer is carefully staggered, compared to the next. The spacing between each layer is varied so a constant high velocity is maintained as the flue gas density changes with temperature. The diameter of the tube also becomes larger as the water temperature increases and steam is produced. In the lower section, the coil forms a water wall around the combustion chamber that minimizes external heat loss. The result is fast heat transfer, even heat distribution and no hot spots. Mechanically, the coil acts like a spring to eliminate the effects of expansion. This allows Clayton Steam Generators to be started and stopped as frequently and as quickly as required without the possibility of mechanical damage. The Clayton Coil is the heart of the Clayton Steam Generator and has benefits that are not available with any other boiler. The Clayton Separator guarantees high-quality steam by combining cyclone separation and screen mist removal. The Separator operates in conjunction with the Clayton forced flow principle to guarantee steam quality of at least 99.5% dry saturated under all load conditions. The separator does not have any moving parts and no maintenance is required. A series of vanes produce a vortex flow pattern that removes water particles by centrifugal action. The separated droplets are collected and recycled. Impurities are simultaneously separated and can be removed by automatically blowing down a very small quantity of the collected water. No other blowdown is required and the total dissolved solids in the incoming water can be as high as 8,550 ppm. The Clayton Separator produces high-quality steam that is the best available from any type of boiler. THE CLAYTON SEPARATOR

The many advantages of using the Clayton Steam Generator is the result of combining three unique and proven technologies.

CLAYTON COIL l Counter Flow Heat Exchanger l No Refractory Insulation l Small Steel Mass l Low Heat Loss l Single Pass Heating l Upfired Burner l Rapid Heat Transfer

CLAYTON SEPARATOR

To produce steam in a Clayton Steam Generator, water goes in one end and high-quality steam comes out the other. The boiler feed water is pumped through the helical water tube coil from the top to the bottom while heat is passed over the coil in the opposite direction. The high efficiency separator at the outlet of the coil ensures that the steam is dry saturated. The principle of forced circulation of water using the Clayton Pump, Coil and Separator is the basis for the many benefits of using the Clayton Steam Generator.

HIGH PRESSURE COMBUSTION AIR BLOWER

AIR/FUEL MIXER

AIR/FUEL DAMPER CONTROL

To meet increasing demands for cleaner technologies, Clayton has created an advanced ultra low NOx burner system available on all our gas-fired steam generator units. The FMB (Fiber Metal Burner) technology achieves ultra low emissions through a combination of improved fuel and air mixing and very low, short flame length. This proven system is automatically controlled and capable of meeting strict local air emissions standards. LOW NOx TECHNOLOGY
